Sometimes authors used Calculus or Laplace Transform in Eng manuscripts to explain his topic,whys it needed?

Question

When I read an engineering or technical manuscript from various published periodicals, sometimes I see high level mathematics like Calculus (differential or integral) or Laplace Transform being injected in the explanation which I find hard to follow, usually boring me and to discontinue reading. What do you think really is the purpose of the author for doing so? Is it not enough to just give the explanation in plain technical language which is easily understandable? Or, is it something of a requirement for an scholarly work? Normally, I skip those mathematics but I wonder how effective it is for others to see at the middle of the paper. I am thinking that the proof or derivation of his findings should not be mixed with the rhetorics and instead be treated separately at the end of the manuscript for the specialists who want to check more in detail his proof.

Perhaps it's a practice that dates back to the ancient Greeks, who developed a methodology for proving Geometric theorems. You've heard of Pythagoras, haven't you?

But I think that calculus or Laplace transforms are put in the body of the manuscript to enable the reader to follow the derivation and proof that has been established by the author. Without proof, the assertions in the manuscript wouldn't amount to a hill of beans!

It is generally the intent of a scholarly manuscript for the author to try to pass on his understanding of a difficult subject. This is best done by taking the reader through the same thought process that the author went through, except you've got the advantage of not having to consider the author's thoughts that led to a dead end.

If you are serious about learning what the author has to say, you should think through each equation as it is presented, until you understand it. You can't skim or speed read here. If this is not what you are after, perhaps you should read Popular Mechanics instead.

It's happening because of unprofessional-ism of writer,because professional can really explain complicated things in easily understandable way.
